Embodiment Construction

[0021] The following describes a method and device for saving system power consumption.

[0022] In the following description, for illustrative purposes, many specific details are given in order to give a detailed understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without these specific details. In other examples, well-known structures and devices are shown in the form of block diagrams to avoid obscuring the present invention.

[0023] Some parts of the following detailed description are given in the form of algorithms and symbolic representations of operations on data bits in computer memory. These algorithm descriptions and representations are the tools used by those skilled in the data processing field to most effectively convey the content of their work to others in the field. Here and in general, the algorithm is considered to be a sequence of self-consistent steps leading to the desired re...

Abstract

A mechanism for conserving power consumption includes a processor, a memory, and a memory control hub ("MCH"). The memory is coupled to the processor and MCH is also coupled to the processor. MCH is further configured to switch between at least two power consumption modes for conserving power consumption.< / PTEXT>

Description

Technical field [0001] The present invention generally relates to the field of computer systems. More specifically, the present invention relates to saving power consumption in computer systems. Background technique [0002] As more systems become portable, they will inevitably rely more and more on portable power sources, especially batteries. As the industry strives to maximize battery life, reducing processor power consumption becomes more and more important. Even in fixed systems, excessive power consumption can lead to higher operating costs. In addition, increasingly stringent government requirements and environmental standards strive to reduce the power consumed in computer systems where possible. [0003] As the clock frequency of each new generation of processors increases, the power consumption of these processors increases as the clock rate increases. Therefore, when the processor consumes a lot of power, the temperature of the processor rises. When the temperature of ...
